The design of the Brother 1034D and Brother 1634D is almost identical. Even when you compare the features, you won’t find more than 2-3 notable differences. So practically, both models are essentially one and the same.

But I’m sure you want me to get into specific details. Every little distinction matters when you wish to buy the best serger.

For example, the Brother 1034D 3/4 Thread Serger is equipped with a single stitch finger. As for the Brother 1634D 3 or 4 Thread Serger has two of those. Even though both models offer removable stitch fingers, this particular difference matters.

Likewise, there are 1 or 2 more such dissimilar characteristics. So let’s discuss them along with the overall design and functionality. Are you ready? Let’s begin.

Brother 1034D vs. 1634D: Serger Comparison

1. Dimension and Weight


The first talking point between the two is dimensions. But this is not a topic that sets one apart from the other. The Brother 1034D 3/4 Thread Serger is around 12 inches tall, 13 inches deep, and 11 inches wide. And so is the Brother 1634D 3 or 4 Thread Serger.

Even the weight of both machines is approximately 13 pounds. Now I know that 13 pounds sound heavy. But that’s the deal with most sergers available on the current retail market. Despite the slightly heavy body, these two units are easy to carry to class. Or move around.

Plus, here’s the thing about more weight. It helps in keeping the machine stable, which is exactly what you need for professional applications.

2. Threading

Are you wondering if either one has the ability to thread itself? In that case, here’s a reason to be disappointed. Both the 1034D and 1634D can’t thread automatically. Manual threading is the norm here. And I know how cumbersome that can get. Especially for first-time users!

Threading sergers is a nightmarish experience. There’s no denying that. It’s not that the initial tries are frustrating; the whole experience can seem like a disaster. But, fortunately, there’s an upside to this. Buying a serger with manual threading means making a wise decision! Allow me to explain below.

If you’re a beginner, it means you get the opportunity to learn how to thread manually. And this can sharpen your amateur sewing skills. That’s because threading demands multiple techniques and experience. And once you get the gist, you’ll never need to relearn. Almost like driving a car!

So let’s compare the manual threading feature of both the Brother sergers. The 1034D consists of a lay-in color-coded threading system. Along with an integrated guide that directs you properly. It shows you how and where to thread the 4 threads. All 4 are coded using different colors, which makes the undertaking easy to carry out.

Now here’s something you might want to know. The fourth and third threads demand more effort and attention. But manual threading has now become comparatively easier to understand. Thanks to high-quality units such as the Brother 1034D 3/4 Thread Serger.

As for the Brother 1634D serger threading, it too comes with an integrated guide. So each thread receives a particular number. However, the 1634D is not as easy and convenient to use as its 1034D counterpart. So in terms of manual threading, the latter is a better choice than the former.

3. Stitch Finger

What is a stitch finger on a serger? It’s the part of stitch creating responsible for working in combination with the others. These include the pressure foot, threads, and needles.

The machine’s pressure foot is located on top of its needle plate. And what the component does is hold the material smooth. To the right side of this pressure foot, lies the stitch finger. It acts as the guide and meeting point for all 4 threads. In order to produce a stitch!

Now you need to remember that the stitch finger is installed very close to the serger’s cutting blade. So it’s a dangerous feature and area for the fingers when the machine is in operation. That means you have to be careful at the time of placing the fingers. Otherwise, you might end up cutting yourself accidentally. (Sewing safety tips)

Read the user manual before changing the settings of stitch finger. Or for troubleshooting any relevant issues!

So how does the stitch finger of the Brother 1634D 3 or 4 Thread Serger compare with the other? This model is supplied with two stitch fingers. As opposed to the one outfitted in the Brother 1034D 3/4 Thread Serger. But both units have removable stitch fingers.

4. Other Features

Apart from threading and stitch finger, there are no other major differences. In terms of operation, the 1034D and 1634D are nearly identical. Each model comes with a differential feed. This feature offers the same optimal ratio that makes room for stitch quality adjustability. For all kinds of fabrics!

The differential feed component is incredibly useful for those who work with various fabrics. Including thin, thick, knitted, and stretchy.

Even stitch width adjustability is the same. And so is the 25-year warranty on limited parts.

The Brother 1034D overlocker performs four-thread and three-thread overlock. It also creates the narrow hem and rolled hem. The same can be said about the Brother 1634D overlocker. Both give you the freedom to buy presser feet separately. So you can perform flatlock, pintucks, and blind hem.

Sergers are considered to be super-fast machines. And all the Brother models are no exception. Especially the 1034D and 1634D. Both work remarkably fast producing 1,300 stitches each minute. You won’t take long to notice how these stitches are nothing but durable and high-quality.


Excellent performance and quality are what I would like to say here. For both the Brother sergers! But only for the sake of comparison, it’s the Brother 1034D 3/4 Thread Serger that ranks slightly better. It is more suitable for beginners. And that’s because of its easier to use and follow manual threading system.

As for the Brother 1634D 3 or 4 Thread Serger, you can opt for this if you’re a little more experienced. But there’s no doubt about or differences in stitch consistency and speed. So you pick anyone without feeling guilty about not choosing the other.
